LASTING AND TACKING MACHINE.

SPECIFICATION forming part of Letters Patent N o. 418,698, dated January 7, 1890. Application filed May 8, 1889. Serial No. 309,982. (No model.)

To @ZZ whom t may concern:

Be it known that we, HENRY WELLINGTON DEAN, residing at Norristown, in the county of Montgomery, and JAMES MUNDELL, residing at Philadelphia, in the county of Philadelphia, both Vof the State of Pennsylvania, have invented new and usefullmprovements in Combined Lasting and Tacking Machines, of which the following is a specification.

Our invention relates to machines for driving tacks in the operation of lasting the upper of the shoe to the inner sole thereof, and in which the last maybe supported upon an ordinary jack; and the object of our invention is to provide a combined lasting and tacking machine in which the tack-driving device and a lasting device pivoted thereto are suspended from the tack-feeding mechanism by means of a flexible tack-feeding tube and controlled by the hands of the operator, whereby the upper of the shoe is drawn in position by the lasting device over the bottom of the last at `such points as the operator may desire to properly lay and crimp the upper, and the tack driven at such point.

Our invention enables an operator to lastV a shoe by hand with pinchers, and at the same time tack the upper by an organized tackdriving machine in which the tacks are fed by a iiexible tube to a universally-movable spring-sustained tack-driving head'suspend-- ed by said tube and containing a driver operated by compressed air or other power. Such a tack-driving machine is described, shown, and claimed in an application iiled by Henry W. Dean, one of the present applicants, of date April 30,188.9,under Serial No. 309,525, and it will be understood that it is the universally-.movable spring-sustained tackdriving head of such machine to which our invention is applied, and by which we obtain the advantage of using a pair of lastingpinchers asa means of controlling the position of a spring-suspended and freely-movable tack-feeding device to drive the tack at the desired point. We prefer to use a springsustained movable tack-driving head, because it facilitates the presentation of the pinchers in taking hold of the edge of the upper on the last, while the iiexible tack-feeding tube, by which the tacks are fed to the driving-head, permits the free movement of the pinchers in relation to the last. The pinchers are connected to the tack-driving head in such manner as to give the operator free use of the same with one or with both hands, and also to manipulate the last in connection with his handling of the pinchers. As stated, the driving-motor for the tack is preferably compressed air, and for controlling its driving action we provide a treadle for operating the valve by which the compressed air is released to drive the tack.

Referring to the accompanying drawings, Figure Vl is a side elevation of the upper p01'- tion of a complete lasting and tacking machine embodying our invention, thev lower portion of the machine being shown in section. Fig. 2 is a View showing the lower portion of the movable tacking-head with the pinchers applied. Fig. 3 is a top View of the pinchers detached. Fig. 4 'is a perspective view of the link for coupling the pinchers to the tacking-head. Fig. 5 isa view, partially in section andpartially in elevation, of a portion of the tacking-head.

The frame A of the machine, the air-pump B, the compressed-air tank C, and the tackfeeding mechanism D are all as shown in said application. The tacking-head E differs only in the mechanism for releasing the compressed air and ,in bringing all the tubes closer to the tacking-head v by means of a band a, so as to' hold it in as nearly a vertical position as possible.

At or near Y the end of theracking-head tube or nozzle b We have attached the pinchers F in the following manner: On the upper jaw of said pinchers we have provided two smalllugs f f, between which is4 pivotally secured the coupling-linkf. The upper end of 'said link is bifurcated, so as to embrace the end o of Athe nozzle of the tacking-head, to which it is pivotally secured by means of two small studs f2, secured to 'opposite sides of said nozzle or tube b, thus admitting of a free movement of the pinchers independently of the taeking-head, and at the same time holding it in its proper relation thereto. This free or universal movement of the suspended pinchers is preferably obtained by arranging the pivotal connections thereof at right angles to each other, and thus permit of holding the pinchers in any position, moving them or inclining in the direction of their length, and turning them at rightangles to such lengthwise movement. This construction permits the movements of the pinch ers within certain limits independent of the suspended tack-driving head for taking hold and pulling the upperproperly over the edge of the inner sole to receive the tack from the nose of the tack-drivin g tube, which is held just at the point of the pinchers, which are pointed to facilitate their movement in relation to the point of the tube. This is importan t, as yit permits the operator to incline, move, and turn the pinchers so as to readily take hold of the edge of the upper just as he wants to and just as it lies around the edge of the last. In addition to this universal movement of the pinchers, they are also free to be swung in any position around the last, and may thus be used with a fixed last. XVe have, however, stated` that the operator has the free use of his hands to manipulate the suspended head and the pinchers, and also to manipulate the lastin connection with his handling of the suspended pinchers, and for this purpose we may use a swiveled mounted last. This construction and co-operative relation of the elements combined, as stated, permits the operator to last the upper and to place the tacks, by reason of his complete control of the nozzle tack-driving head, the pinchers, and the last by his hands, while by his foot he controls a valve for the release of the airpower for driving the tacks. This, so far as we know and can tind, has never been done before.

le have shown and described au eicient means, consist-ing of compressed air, as the power for driving the tacks, and we prefer to use such power; but other power may be used as the means for driving t-he tacks without departing from the spirit of our invention.

The interior of the taeking-head E and of the valve a for releasing the compressed air are constructed and arranged as in said application above referred to; but, instead of the hand-lever for releasing the valve a', we have connected to the valve-stem a2 a small piston a3, housed in a small cylinder at at the top of and to the one side of the tacker E. Connected to this cylinder a4 is a rubber tube a, which passes up over and down through a portion of the frame of the tack-feeding mechanism D to the compressed-air tank C, and is connected to said tank by means of a valve c. This valve c has a small stem c for opening and closing the same, and to which is fastened a rod c2, which at its other end is connected to the treadle c3. The treadle is held in its normal or raised position by means of a strong spiral spring e4. Now, it is obvious that the operator can use one hand to manipulate the pinchers and have his other hand f ree to handle the last, as he may desire, and by depressing the treadle c3 with his foot the valve c will be opened, which will allow the compressed air to pass up through the tube ai and press down the piston a3, which will open the slide-valve a', and thus drive the tack. On releasing his foot from the treadle, the spring e4 will cause it to rise to its normal position, and, by means of the rod c2, close the valve c, and thus shut off the compressed air from the tube a5. The piston a3 is raised to its normal position by means of the spiral spring a on the valve-stem o?.

G is the flexible tack-feeding tube by which the universal]y-movable tack-driving head is suspended, and we prefer to construct this tube with a spring H, by which it is suspended from the frame of the tack-feeding mechanism, it being understood that the connecting of the tack-feeding tube with the de livery end of the tack-feeding raceway is such as to allow said tube to have a verticallyyielding function with the spring, and that the latter has a balancing function for the tack-driving head. y

As a hand apparatus, a pair of pinchers and tack feeding and driving mechanism have been combined, the tacks being driven by hand, and the tack feeding and driving mechanism being rigidly connected with and mounted directly upon the upper jaw of the pinchers; but it is obvious that such a device could not be attached to or combined with the pneumatic universally -movable tackdriving head herein shown and described.

Ve are also aware that a pair of lastingpinchers have been pivotally mounted upon the end of a horizontal bar operated by the treadle for seizing the edge of the upper and pulling it over the edge of the inner sole to receive tacks, both placed and driven by hand; but it is obvious that such a device could not be attached to or combined with the pneumatic universally-movable tack-driving head herein shown and described.

Our invention embraces two well-known devices in combination, and which, in their conjoint co-operation, produce a new lasting and pneumatic tack-driving machine, in which both the driving device and the lasting device are each capable of universal movement and operation as an entirety not before known or used, and giving the advantages of quick and easy lasting by hand with a pneumatic driver operated by a treadle.
